Abstract
A method for minimizing evaporative fuel emissions of a vehicle having an internal combustion engine, the engine having a combustion chamber, a corresponding fuel injector and a throttle valve assembly in cooperation with a corresponding intake manifold, the method including the step of storing fuel vapors that emanate from the engine to prevent “upstream” migration of the fuel vapors from the engine through the throttle valve assembly. The stored fuel vapors can then be released back into the engine for combustion thereby avoiding release into the atmosphere.
